POLISHING-BRUSH.

SPECIFICATION forming part of Letters Patent No. 299,873, dated June 3, 1884.

Application filed April 7, 1884. (No model.)

To all whom it may concern.-

Be it known that I, WILLIs A. Srnvnns, of Wallingford, in the county of New Haven and State of Connecticut, have invented a new Improvement in Polishing-Brushes; andI do hereby declare the following, when taken in con nection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and eXact description of the same, and which said drawings constitute part of thisspecification, and represent, in

Figure 1, a longitudinal section of several disks as secured to the head; Fig. 2, a sectional face view of one of the disks, showing a single tuft as secured therein 5 Fig. 3, an edge view of a single disk.

This invention relates to an improvement in that class of brushes employed for polishing metal surfaces, and such as are usually made from'fine wire projecting radially from a hub arranged upon a spindle to revolve rapidly, and so that the surface of the metal applied to the projecting wire will be polished. Such brushes are largely used in polishing plated ware.

The object of the invention is a simple'and cheap construction of the brush, and whereby the shape of the brush maybe changed as oocasion may require; and the invention consists in a disk or series of disks having radial holes in the periphery, into which the doubled end of the wire tufts may be set and a pin introduced transversely through the disk and holes and over the bend of the wire, and so as to hold the tufts firmly in place, as more fully hereinafter described. The disks A are made from metal. (Shown detached in Figs. 2 and 3.) They are in thickness a little greater than the diameter of the tufts at the bend. These disks are constructed with a central hole, a, to fit upon the spindle B. Into the periphery of the disks several holes, I), are bored, in diameter corresponding to the tufts C at the bend, and transversely through the disk at these holes smaller holes, (I, are bored, and distant from the bottom of the hole equal to the thickness of the tuft at the bend, as seen in Figs. 1 and 2. The tufts are made from fibers of wire of suitable length, doubled, the bend intro duced into the holes I). and then a pin, a, introduced through the holes (I and over the bend of the tuft, as seen in Figs. 1 and 2. The hole embraces the body of the tuft at the bend, and the pin passing over the bend or be tween the double serves to secure the tuft firmly in its place. Several of these disks thus prepared may be placed upon a spindle, B, as seen in Fig. 1, and secured. The spin dle as represented is a screw havingalongitudinal spline, f, and the hole through the disks having a corresponding recess, so as to prevent the disks from turning on the spindle. The screw-spindle binds the several disks to the head D.

Disks of various shapes may be employe;l say gradually diminishing, as seen in Fig. 1, whereby a sphericalshaped brush will be produced; or they may be of equal diameter, but of any desired shape or number. XVhenever the wires or a portion of them are worn or otherwise become defective, they may be readily removed by taking out the pins 6 and new tufts introduced. The disks, not being affected by the wear of the brush, may answer for long-continued use by being repaired or worn tufts restored.

I claim- The herein described brush, consisting of one or more metal disks, A, the periphery of the disks having holes or recesses to receive the doubled ends of tufts, the tufts doubled and introduced into said holes, and a pin, 0, transversely through the disks and over the bend of the tuft, substantially as described.
